Fas

Alpha-Cypermethrin: Mechanism and Efficacy

The «Fas» insecticide by Ukravit relies on alpha-cypermethrin, a second-generation pyrethroid known for its rapid "knockdown" effect. It works by disrupting the sodium channels in the nerve membranes of target insects. Practically, this triggers an immediate cessation of nerve impulses, leading to the paralysis and death of the pests shortly after exposure. Because the product is a contact-type insecticide, it is essential for quick-response interventions when pest populations reach economic injury levels.

Technical Formulation and Performance

The choice of a suspension concentrate formulation is a significant engineering decision. Unlike standard emulsions, this formulation ensures greater stability in the spray tank and superior film formation on the leaf surface. This is vital when treating crops like rapeseed or cabbage, which often possess waxy cuticles that repel conventional solutions.

• Broad Spectrum Control: The product is highly effective against a variety of pests, including rape blossom beetles, flea beetles, cereal leaf beetles, sunn pests, and aphids.
• Precision Application: With a recommended rate of 0.1–0.2 L/ha, growers can adjust their dosage based on the pest pressure. Applying the upper limit of the range ensures thorough penetration in dense vegetative canopies.
• Strategic Use: Classified under Hazard Class 2, the product demands strict safety adherence. It allows for up to 2 applications per season, making it an excellent component for integrated pest management and resistance-breaking rotations.

By applying «Fas» during the vegetative stage, farmers can effectively preserve the photosynthetic area of their crops, protecting the yield potential of winter wheat, rapeseed, and cabbage. The biological activity of the alpha-cypermethrin remains stable even under varied environmental conditions, ensuring consistent results in the field.
